"There are 120 'days' of these combinations and a “workbook” page to use to reinforce the information. The idea is to look up these words and expressions, write down the definitions, write the spelling word as many times as it takes to learn it, fit the word pairs into sentences, define the idiom and how you would use it — all intended to be accomplished in 20 minutes or so a day. That would be 20 fun-filled, challenging, and interesting minutes each day."
